- This diagram shows how we can use Proxy ARP to pass a public IP through the edgemarc and directly to the customer's data firewall. This allows the customer's data firewall to maintain a public IP so they can do any port forwarding, NATing, Client VPNS, etc. that they want to without the edgemarc interfering. 
    
- It allows us to keep QOS policies on the Edgemarc in place, and keep a dedicated percentage of the bandwidth reserved for VoIP traffic. This helps significantly with Call Quality. A guide on how to set this up can be found in the HUDU Global Wiki.
